6 Configuring Oracle Exadata Database Machine

This chapter describes how to configure the system, accounts, and software for Oracle Exadata Database Machine.

Note:

• For ease of reading, the name "Oracle Exadata Rack" is used when information refers to both Oracle Exadata Database Machine and Oracle Exadata Storage Expansion Rack.

• The procedures in this chapter are applicable to Oracle Exadata Storage Expansion Rack as well as Oracle Exadata Database Machine.

• The procedures in this chapter use the information from Oracle Exadata Database Machine Deployment Assistant (OEDA). Be sure to run OEDA before starting the procedures in this chapter.

• Verifying the Network Configuration Prior to Configuring the Rack
  Use the checkip.sh script to ensure there are no IP address conflicts between the existing network and your new Oracle Exadata Rack.
• Configuring the RDMA Network Fabric Switch
  You must perform an initial configuration of the RDMA Network Fabric switch.
• Setting the Subnet Manager Master on Oracle Exadata Database Machine Full Rack and Oracle Exadata Database Machine Half Rack
  
• Configuring the Management Network Switch
  You must perform an initial configuration of the Management Network Switch.
• Configuring the Power Distribution Units
  The power distribution units (PDUs) are configured with a static IP address to connect to the network for monitoring.
• Configuring the Threshold Settings for the Power Distribution Units
  
• Checking Exadata Storage Servers
  After powering up the rack, check the Oracle Exadata Storage Servers.
• Checking Oracle Exadata Database Servers
  Before installing the software, check the configuration of the Oracle Exadata Database Servers.
• Performing Additional Checks and Configuration
  Perform these additional checks and steps to verify the configuration of your Oracle Exadata Rack.
